This is clearly one of those "I've missed the basic principle" type issues. Luckily since everything is now "on the web" I can be very specific and not need to say "for example" (but it's the principle I want to understand).

[FYI: This got moved from "stackoverflow" because it's not about programming ... strictly true I guess ... but mostly for programmers ]

[AFYI: It seems some folks go around searching keyword matches on questions , then posting links to any that match ... so I've already found many links were people did a merge from another repo ... and it worked ...if that was the answer I'd not have posted this question]

I developing some code to drive an e-ink display. The code is at:

https://github.com/waveshareteam/e-Paper

I came across a bug and went to open an "issue" , while there I spotted there were quite a lot of "issues" and a lot of waiting "pull requests". Reading though these I realised I'd quite like some (one for now) in my version.

The one I wanted was : https://github.com/rohoog/e-Paper

(lots of fixes to avoid busy waits)

...Now I didn't do this is the methodical fashion implied here but:

`git clone https://github.com/waveshareteam/e-Paper

git remote add rohoog https://github.com/rohoog/e-Paper

git fetch rohoog --tags

graeme@waveshare:~/src/e-Paper-Updated-GIT$ git branch -r WARNING: terminal is not fully functional Press RETURN to continue

origin/Development origin/HEAD -> origin/master origin/master rohoog/develop rohoog/master rohoog/rohoog/array_overflow rohoog/rohoog/bmp-reading rohoog/rohoog/compile-opt rohoog/rohoog/no-commit-binaries rohoog/rohoog/wait_pin

git checkout rohoog/master find RaspberryPi_JetsonNano > /tmp/rohoog-master-RaspberryPi_JetsonNano git checkout master find RaspberryPi_JetsonNano > /tmp/origin-master-RaspberryPi_JetsonNano diff /tmp/origin-master-RaspberryPi_JetsonNano /tmp/rohoog-master-RaspberryPi_JetsonNano`

... diff them, there are lots of differences.

next

git diff origin/master rohoog/master > /tmp/diffs

graeme@waveshare:~/src/e-Paper-Updated-GIT$ wc /tmp/diffs 561055 1374852 25309866 /tmp/diffs

(so maybe , I'll regret trying to do this ...but let's see ..I only care about a few files)

graeme@waveshare:~/src/e-Paper-Updated-GIT$ git branch WARNING: terminal is not fully functional Press RETURN to continue

• master

graeme@waveshare:~/src/e-Paper-Updated-GIT$ git merge rohoog/master Already up to date.

OK...what! , how ? I can see many people have had similar "blind spots" but it feels like I've followed the guidelines ... what am I doing wrong?

Well there are many thousands of lines different I'd expect something to get changed?
